The Batarangs in question are made out of metal and at the press of a button deploy the two wings ready to help take out the Joker. If this wasn’t enough the video even explains how to make your own Batarangs! We recommend that if you do make some, you don’t start wearing black spandex and prowling the streets at night, instead enjoying what is, without a doubt, one of the coolest creations we have ever seen.

We now have a Batarang and you can even get a Batmobile golf cart. What piece of fantasy technology would you like to see made and why?
